Spencer and Ruben both have aquariums in their rooms now. Each day they observe their fish. They interpret the fish behaviors and watch their patterns of swimming, resting, and interacting with other fish. It is especially fun to look in the tank when the room is dark. The fish tank is a big bedtime procrastination. Though at first I thought it to be a distraction, now I see it as a way for the two boys to calm down, be quiet, & just watch. Then get into bed, turn out the light, and watch the tank from bed as their eyes get very heavy, until they fall asleep. Kind of peaceful to have a piece of nature in your room. Calming to hear the water trickle through the filter, and just plain fun to have a tank of little fish to care for.
